Weather in Mirny

Planning your day or a trip to Mirny? Familiarise yourself with the current meteorological conditions, detailed forecasts, and temperature charts right here.

The climate in which Mirny is situated can be described as sharply continental. This means that colossal temperature fluctuations are observed between seasons: from extreme frosts in winter to quite comfortable warmth in summer. The Russian Federation reveals its rugged northern nature in this region, so travellers should carefully consider their wardrobe choices depending on the time of year.

Winter here is very long and cold, occupying the majority of the year. In December and January, average temperatures drop to -30°C, and sometimes even lower, requiring serious preparation for the trip. There is little precipitation during the winter period, but the low temperatures keep the snow cover intact for a long time.

Summer, on the contrary, is short but sufficiently warm and sunny. The most pleasant month is July, when the air warms up to +18°C...+23°C. This is the best time to explore the city without extreme weather conditions. The transitional seasons fly by rapidly: spring and autumn are very brief, characterised by a quick shift in the temperature regime.

The climate in this region is distinguished by a pronounced continental character with extreme temperature swings throughout the year. Mirny is known for its severe and prolonged winters, which are a true test of endurance. The coldest months are January and December, when average figures drop to -29.6°C, and nightly frosts regularly reach the -33°C mark. February is only slightly less severe, maintaining an average temperature of around -25°C. This time requires travellers to wear the warmest clothing and prepare thoroughly for their journey.

Summer here is short, but can be surprisingly pleasant and comfortable, creating a sharp contrast with the winter chill. The hottest and most favourable month of the year is traditionally July: during the day, the air warms up on average to 23.1°C, allowing you to enjoy walks without the exhausting heat often found in warmer climates. June and August also delight with mild warmth, with average values ranging from 15°C to 17°C. However, daily fluctuations should be taken into account: even at the height of summer, nights can be quite fresh, with temperatures around 10-12°C.

Transitional seasons are characterised by rapid weather changes. Spring arrives quite late: confident frosts of around -14°C persist in March, and stable positive temperatures are established only by May. Autumn arrives just as quickly: while you can still catch relatively warm days in September with an average temperature of 5.5°C, negative values return by October, and November greets guests with a full-blown winter with average figures around -19.5°C.

The climate in the city of Mirny is characterised by a small total amount of precipitation, the nature and type of which depend heavily on the time of year. The winter period, lasting here from November to March, is distinguished by severe frosty weather, so precipitation falls exclusively as snow. Despite the fact that the snow cover remains for a long time, intense snowfalls are practically non-existent: February is considered the driest month, when on average only about 3 days with precipitation are recorded.

With the arrival of warmth, the picture changes, and rains come to replace the snow. Summer months, especially July and August, as well as the beginning of autumn, bring the greatest number of wet days — from 9 to 10 per month. However, even during this period, when Russia displays its climatic contrasts, rains in Mirny are rarely torrential; more often, they are short-term or moderate showers that merely refresh the air slightly.

The gloomiest and wettest month, according to statistics, is October: at this time, the number of days with precipitation reaches 11. This is a transitional period when autumn rains gradually begin to mix with wet snow, heralding the imminent arrival of winter. Travellers should note that, although the volume of falling moisture is small throughout the year, an umbrella or raincoat may be useful specifically during the summer-autumn season.

When packing for Mirny, it is important to consider the severe nature of the local climate. Winter here is long and extremely cold: from November to March, the thermometer consistently stays below the -20°C mark, and in January and February, frosts often reach -30°C and lower. For a trip during this period, a set of high-quality thermal underwear, wool socks, a down jacket with natural insulation, or a special parka designed for northern conditions is vital. Do not forget a warm hat, scarf, and mittens, and choose footwear with thick soles and natural fur lining.

Summer in this corner, which is part of the country of Russia, is short but can be quite pleasant. In June and July, the air warms up on average to +17...+23°C, so you will find t-shirts, light jeans, and comfortable trainers useful for walking. However, even in summer, nights can be cool, so be sure to take a fleece jacket or a windbreaker with you. Given that the number of rainy days is small, heavy raincoats are unlikely to be needed, but light protection from the wind will not go amiss.

In the transitional seasons (April, May, September, October), the weather changes rapidly, so the best strategy is the principle of layering. This will allow you to remove or put on items depending on the temperature, which can fluctuate from freezing to positive values within a single day. It is also worth bringing sunscreen and sunglasses: in winter, the snow actively reflects the sun, and in summer, UV radiation can be quite active even with moderate heat.
